Abstract
The Abundance of Forensic Insects on Dog and Rabbit Carcasses in Different Habitats and Developmental Stages of Chrysomya albiceps as a Forensic Indicator
Highlights
Entomological evidence on cadavers has been demonstrated to help in elucidating homicides, ranging from the determination of the post-mortem interval (PMI) to indications of the local of the crime (Catts and Goff, 1992)
According to the number of occurrences of the different adult insect species collected in dog carcasses placed outdoor were arranged as follows: Chrysomya albiceps (1679), followed by Musca domestica (1151), Dermestes maculatus (417), Piophila casei (224), Hister sp. (117), Monomorium pharoensis (87), Musca sorbens (81), Necrobia rufipes (69), Sarcophaga carnaria (60), Nasonia vetripennis (59), Calliphora sp. (44), Wohlfahrtia magnifica (42), Megaselia scalaris (34), Chrysomya megacephala (31), Lucilia sericata (29), Vespa orientalis (15), Creophilous maxillosous (14), Stomoxys calcitranas (9), Dolichovespula sp. (9), Cataglyphis bicolor (6), and Phormia regina (3)
The number of occurrences of insect species collected in dog carcasses placed indoor were arranged as follows: Nasonia vetripennis (571), followed by Chrysomya albiceps (459), Dermestes maculatus (304), Musca sorbens (199), Megaselia scalaris (57), Necrobia rufipes (50), Monomorium pharoensis (40), Hister sp. (32), Musca domestica (31), Sarcophaga carnaria (21), Calliphora sp. (5), Creophilous maxillosous (3), and Wohlfahrtia magnifica (2)
Summary
Entomological evidence on cadavers has been demonstrated to help in elucidating homicides, ranging from the determination of the post-mortem interval (PMI) to indications of the local of the crime (Catts and Goff, 1992). This study aimed to characterize the insect species present on cadavers and to estimate the postmortem interval (PMI) by studying the developmental stages of the first flies arrive at the carrion. These data should contribute to the creation of a database of forensic insects in Egypt. Nasr city is considered a semi-arid urban region It has four distinct seasons; winter, spring, summer and autumn. The sites for carcass placement were chosen in a botanical garden (outdoor) of the animal house and in the laboratory (indoor) at the Department of Zoology and Entomology, Faculty of Science, Al-Azhar University. One dog and one rabbit carcasses were placed in the laboratory (indoor) and the other two carcasses were placed in a botanical garden (outdoor) of the animal house
